* | crypto: omap-sham - irq and dma handling changesDmitry Kasatkin2011-06-29
| | | | | | | | | | | | | | | | | | | | | | | | It could be a situation, that tasklet is executed twice because of certain delay between dma callback and irq handler execution. In that case, second tasklet execution could actually corrupt the data of the new started dma transactions. This patch improves tasklet logic and prevents above described cases.

* | crypto: omap-sham - remove dedicated queue handling taskletDmitry Kasatkin2011-06-29
| | | | | | | | | | | | | | | | | | | | | | | | Calling omap_sham_handle_queue from "done" tasklet should be done after irq scheduled tasklet completes. Having additional tasklet does not solve that issue because it might be execute before. So queue handling tasklet has been removed and functionality integrated into single tasklet.

| | | | | | | | | | | | | | | | | | | | Some flags are changed in interrupt handlers and verified in the tasklet. There might be a race condition when tasklet is interrupted or another cpu/core will run IRQ handler and tasklet in parallel. Atomic bitops functions are now used instead of bitmask operations.

| * crypto: caam - fix decryption shared vs. non-shared key settingKim Phillips2011-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Key sharing is enabled by default in the shared descriptor. Using CBC decrypt, AES has to alter the key in order to decrypt. During high traffic decryption rates, i.e, when sharing starts to take place, we need to use a different OPERATION option to tell AES that the key was already altered by the PRIOR descriptor - we need the following kind of logic: if ( shared ) operation where AES uses decryption key (DK=1) else operation where AES uses encryption key (DK=0) this patch implements this logic using a conditional and a non-conditional local jump within the decryption job descriptor.

| * crypto: omap-sham - hmac calculation bug fix for sha1 base hashDmitry Kasatkin2011-04-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes 2 hmac inter-dependent bugs. 1. "omap-sham: hash-in-progress is stored in hw format" commit introduced optimization where temporary hash had been stored in OMAP specific format (big endian). For SHA1 it is different to real hash format, which is little endian. Final HMAC value was calculated using incorrect hash. Because CONFIG_CRYPTO_MANAGER_TESTS was disabled this error remained unnoticed. After enabling this option, bug has been found. 2. HMAC was calculated using temporrary hash value. For a single-request updates, temporary hash was the final one and HMAC result was correct. But in fact only the final hash had to be used. All crypto tests for HMAC produces only single request and could not catch the problem. This problem is fixed here.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SPAcc's have 2 equally sized FIFO's - a command FIFO and a status FIFO. The command FIFO takes the requests that are to be performed and the status FIFO reports the results. It is possible to get into the situation where there are more free spaces in the command FIFO than the status FIFO if we don't empty the status FIFO quickly enough resulting in a possible overflow of the status FIFO. This can result in incorrect status being reported in the status FIFO. Make sure that when we are submitting requests the number of requests that have been dispatched but not yet popped from the status FIFO does not exceed the size of a single FIFO.
